Abstract: A system and method that sequences product to increase machine throughput. A plurality of input feeding devices each randomly receives products from a stream of product. A plurality of output groups corresponding to the plurality of input feeding devices are provided during a first pass phase and a second pass phase. The plurality of input feeding devices feed the product to output bins of the plurality of output groups. A control has a first mode of operation and a second mode of operation for a first pass phase and a second pass phase, respectively. In the first mode, the control allows all input feeding devices of the plurality of input feeding devices complete access to all output groups of the plurality of output groups during the first pass phase. In the second mode, the control constrains placement of the products to output groups assigned in the first pass phase such that the groupings of the products to the assigned output groups remain constant between the first pass phase and the second pass phase.

Abstract: A system and method that sequences product to increase machine throughput and capacity. The system includes a plurality of input feeding devices each randomly receiving product received from a stream of product and a plurality of output groups each having output bins. A control has a mode which constrains the input feeding devices to (i) feeding non-rejected product from the stream of product to assigned output groups of the plurality of output groups associated with a corresponding one of the plurality of input feeding devices based on a code associated with each of the product, and (ii) feeding rejected product to at least one output bin in a single group of the plurality of output groups such that each of the plurality of input feeders has access to the at least one output bin. The method includes feeding the non-rejected and rejected product to appropriate output bins such that the rejected product is provided to an output bin which is accessible by any of the input feeding devices.

Abstract: An embodiment of the invention provides a system and method for creating a learning map, which is a device for expressing hypothesized learning target dependencies within any domain of knowledge of skill acquisition. The system and method are also able to utilize multiple data types and sources to assess whether the learning target dependencies expressed by a learning map are accurate and are configured to modify the learning map as necessary so that the learning map conforms to the reality of how students learn.

Abstract: An improved singulation mechanism is provided for flat articles having significant variations in size, thickness and weight, which mechanism utilizes at least two vacuum chambers positioned behind a moving perforated to feed the articles and selectively controls at least one of pressure and flow for at least one of the chambers to facilitate the feeding of heavier articles, while inhibiting bleed through doubles for lighter articles. A mechanism may be provided which provides a puff of air to at least one of the chambers at the end of the operation thereof to reduce the feeding of doubles and a bent fence may be suitably positioned to both facilitate feeding of shorter articles and to facilitate proper initial alignment of the articles.
